Abstract : The Competition Analysis Model, CAM, is designed to provide computational and analytical support to decisions on competition strategy and provide support throughout the life of a project. It is useful for decisions both early in the acquisition cycle and as a foundation for later detailed analyses at both the prime system level or for subsystems and components. CAM does not extrapolate from past experience, but outlines an approach to structuring competition based upon goals and relevant data. The Competition Analysis Model consists of three volumes (CAM Analysis Guide, CAM Computer Manual, and program Maintenance Manual) and a disk containing the BASIC code for IBM-PC or PC compatible computers. This volume, CAM Analysis Guide, provides a full discussion of input parameters, the computational procedures and the economic issues underlying them. (Author)
